And "coffin dwellers will be allowed to bring a friend along during Fright Fest operating hours, but they must brave the non-operating hours alone," a Six Flags press release reads. "Well, not exactly alone, some of our Fright Fest Freaks will be lurking about in the darkness."

Potential participants can fill out a registration form to see if they can compete. Those who survive the claustrophobically creative contest will be placed in a drawing for a $300 prize if there are multiple people who make it the whole time. They will also receive two 2019 Gold Season Passes, a Fright Fest prize package, two VIP Haunted House passes, and a ticket for two to ride the Freak Train for Freak Unleashed. The coffin is also available to take home if the winner so chooses.

Park-goers must be 18 years old to take part in the competition, and need to bring their own pillows and blankets if they want to get more comfortable. Cell phones are allowed, as phone charging stations will be provided for possible use within the coffin, according to the St. Lous Post-Dispatch.
